JOHN M. PYRON', OF WILLS POINT, TEXAS.

SAFETY-PIN.

Specification of Letters Patent.

Patented Au 25, 1914:.

Application filed June 18, 1912. Serial No. 7043M.

To all whom it may concern Be it known that I, JOHN M. PYRoN, a citizen of the United States, residing at Nills Point, in the county of Van Zandt and State of Texas, have invented new and useful Improvements in Safety-Pins, of which the following is a specification.

My invention relates to safety pins, the main object being the provision of means for preventing longitudinal movement of the pointed leg of the pin when in operative position.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawing, which forms a part of this application and presents a perspective view of the pin, the pointed leg of the same being shown in its inoperative position.

In the drawing, the pin is shown as being constructed so that its shield 27 is U-shaped in cross section and has its inner edge inbent to form a ridge 28. A band 29 of metal embraces the shield 27 and is adapted to slidably move thereon. The cross portion 80 of the band 29 has its outer edge bent inwardly to form a ridge 31 which is adapted to be positioned directly opposite the ridge 28 in the outer member of the shield when the inner member or band 29 is slid into its inner, operative position. A portion of the member 29 is out-struck as at 32 to form an internal indentation for the reception of relatively spaced, out-struck projections 33 formed on the outer member 27 of the shield and located in the path of the indentation on the slidable member, so as to lock the same in either its operative or its inoperative position. The pointed leg 34. of the pin is provided adjacent its extremity with directly opposite inner and outer notches 35 and 36 respectively, which are adapted to be received by the ridges 31 and 28 respectively on the shield members.

From the foregoing description, it should be apparent that the pointed leg of the pin may be locked effectively against longitudinal movement with respect to the shield whereby it is prevented from being bulged outwardly to such an extent that its point will become disengaged with the shield during its use as a garment fastening device.

I claim 1. A safety pin comprising a wire bent to form the legs of a pin, a shield provided upon one of said legs and including a fixed member substantially U-shaped in trans verse section, a transverse rib provided within said fixed member, a yoke-shaped movable member mounted for longitudinal sliding movement upon the fixed member and having a cross portion bridging the longitudinal edges of the fixed member, and a transversely extending, inwardly projecting rib formed upon the cross portion of the movable member, the said ribs forming jaws for engagement with the opposite leg of the pin.

2. A safety pin comprising a wire bent to form the legs of a pin, a shield provided upon one of said legs and including a fixed member substantially U-shaped in transverse section, a transverse rib provided within said fixed member, a yoke-shaped movable member mounted for longitudinal sliding movement upon the fixed member and having a cross portion bridging the longitudinal edges of the fixed member, a transversely extending, inwardly projecting rib formed upon the cross portion of the movable member, the said ribs forming jaws for engagement with the opposite leg of the pin, and an outward projection being formed upon one side of the fixed shield member, an indentation being provided within the corresponding side portion of the movable member for engagement with the said projection.

In testimony whereof I aifix my signature in presence of two witnesses.
